Algebra Lesson 6.11: Properties of Addition

In this video, Mr. War introduces a math lesson on the properties of addition, focusing on the commutative and associative properties. He explains how these properties can be used to add fractions with unlike denominators. The video includes example problems demonstrating the application of these properties, followed by practice problems for viewers to solve. The lesson aims to help students understand and apply these properties to simplify addition problems involving fractions.
